INTRODUCTION. 
I N Indian high forests, generally abnormal in type, the selection 
system in one or other of its many modifications is nearly 
universally applied in Indian Working Plans, in calculating the 
possibility and prescribing the felling operations. The object of 
this monograph is, firstly, to bring together in a concise form the 
different modifications or methods which have sprung up in the 
various provinces of India, giving detailed examples from existing 
working plans ; secondly, to contrast them ; and finally, to indirectly 
indicate the advisability of prescribing a standard system for the 
whole of India for the calculation of the possibility by number of 
trees, and by tiie volumetric method respectively.
